Mumbai is our home base — we're headquartered on Charni Road, and it's where we've installed the widest range of our TOSTEM window and door systems, from South Mumbai redevelopment towers to suburban high-rises.
It's also one of the toughest environments in India to build a window for. Coastal salt air corrodes untreated metal fast, the monsoon drives rain sideways into window seals for weeks at a stretch, and a city built mostly of high-rises means every opening has to handle real wind load, not just weather.
What matters on site here.
Salt-Air Corrosion Resistance
Coastal salt air attacks untreated aluminium and steel over time. Our TEXGUARD-coated frames and corrosion-resistant steel entrance doors are built to hold their finish through Mumbai's humidity, not just look good on installation day.
Monsoon-Ready Sealing
Wind-driven monsoon rain finds every gap in a poorly sealed window. EPDM gasket sealing on every unit keeps water out during Mumbai's heaviest weeks of the year, not just light showers.
Traffic & Construction Noise
Dense traffic and the constant hum of redevelopment construction are a daily reality in most Mumbai neighbourhoods. Sealed frames and optional double glazing cut that noise well below what a standard window achieves.
High-Rise Wind Load
Upper floors of Mumbai's towers see meaningfully higher wind pressure than street level. Our systems are tested to ASTM and AAMA wind-load standards, not sized only for low-rise conditions.
Where to start.
Sliding Windows
Space-saving for tighter Mumbai floor plans, with sealed tracks that resist salt-air corrosion.
Tilt & Slide Windows
A tilt position for ventilation without fully opening a high-rise balcony window to wind.
GIESTA Steel Entrance Doors
Anti-rust coating and multi-point locking suited to ground-floor and podium-level entrances.
